Regardless of whether you want to call it a wave, the fight for the House continues to creep into Democratic territory.

Many of the Republican incumbents who were expected to have challenging races this cycle, including New York Rep. Chris Gibson, Colorado Rep. Mike Coffman and Illinois Rep. Rodney Davis, are starting the general-election sprint in stronger-than-expected position. Also, some Democratic incumbents, such as New York’s Dan Maffei, are in much closer races than anticipated. And now some hot spots, such as Hawaii’s 1st District, are popping up as potential Democratic headaches and look vulnerable.
